Respuesta :
Regular use of opioids may reduce the brain's production of endorphins.
This classification of drug typically changes the brain's chemistry and
reduces its ability to create its own endorphins.
options:
Stimulants
Depressants
Hallucinogens
Narcotics
I believe the answer is Hallucinogens but Hallucinogens can be considered to be Narcotics so its out of those two.
